About Us:
Essential Software began focusing on high-quality software maintenance services in 199X, in conjunction with a request from KLA Tencor. While our focus is relatively recent, Essential Software has been in software business since 1990 gathering experience as a provider of contract software services. In 199X, working with KLA Tencor Essential Software was literally transformed from a successful software-contracting house to a provider of software maintenance outsource services. We have been growing ever since.
Our engineering team is based and grown from the heart of Silicon Valley, which provides customers the ability to locally outsource complex projects to a team of engineers that have extensive experience in software maintenance and understand the need for rapid analysis and programming of high quality products.
